To Di Mainstone, a suspension bridge isn’t just for walking or cycling over. It’s also a musical instrument.

The British artist translates the vibrations of bridge cabling to audible sound, turning infrastructure into something tuneful. A “movician” dancer/musician pulls strings through different attachments to the bridge, creating a variety of effects.

“One by one she awakens the bridge’s suspension rods with a tap of her song-spoon and they issue a loud metallic yawn,” says the artist, talking of the movician. “She pauses by the rod which supplies the most pleasing tone, and watches as her bridge-playing apparatus jumps from her bag and attaches itself to the bridge’s soaring white shaft.”
